Improvement in wagon-springs



UNITED STATES JOSEPH O. FARRELL, OF BOSTON, ASSIGNOR TO HIMSELF, AND \VM. VEAZEY,

PATENT OFFICE.

OF GAMBRIDGEPORT, MASSACHUSETTS.

IMPROVEMENT IN WAGON-SPRINGS.

Specification forming part of Letters Patent No. 34,858, dated April 1, 1862.

To all whom it may concern.-

Be it known that I, J OSEPH O. FARRELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented anew and usefulImprovementin Side-Spring Wagons; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in Which Figure 1 is a plan or top view of the running-gear of a wagon with my improvement attached to it. Fig. 2 is a side sectional view of the same, taken in the line aor, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to that class of vehicles known as side-spring wagons, or those that have the body attached to horizontal springs extending longitudinally beneath the body, one at each side and parallel with each other. These springs have hitherto been rigidly attached to their axles, and have consequently caused the latter to be subjected to a great strain, a contingency which the within described invention is designed to-avoid.

Another objection that attends the employment of the common side-spring vehicle. is that the body, when loaded, falls too low for convenient use.

In carrying out my improvement I attach one end of the springs rigidly to one axle, while the other ends are connected to the other axle b y means of shackles, substantially as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A A represent the front and back axles of a light pleasure-wagon.

B B represent reaches; O, the wheels.

D D are the side springs, the front ends of which are provided with eyes a, which are fitted on horizontal pins 1), attached permathe springs D D to yield or give without straining the axles A A. This will be fully understood by referring to Fig. 2, in which one springD is shown depressed, in red. The bars F do not admit of being forced outward or backward, except as the springs D are depressed. The bars therefore do not in the least detract fro m the efticiencyof the springs, but only serve to allow themto yield or give under the load to which they are subjected without exerting any strain or lateral pressure against the axles, a contingency which occurs in the ordinary mode of construction, owing to the direct connection of the spring to both axles.

I do not claim, broadly, the use of shackles in connection with springs; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The construction of side-spring wagons with the rear ends of the springs D D jointed to curved arms F, which are also jointed to the hind axle, all. as herein shown and described.

JOSEPH O. FARRELL.
